Vaccination Campaign Aims to End Polio in Gaza

The interesting thing about modern air travel is that what used to be a local disease can now spread worldwide within a matter of hours or days.
FWIW, I knew someone who had polio as a child. Wiped out a few back muscles forever.
Are there any stocks that would benefit if we had to go back to iron lungs, which they used in the bad old days before the vaccine was created?
